LIMITED WARRANTY AND LIMITATION OF LIABILITY

Each Fluke product is warranted to be free from defects in material and workmanship under normal use and service. The warranty period is two years and begins on the date of shipment. Parts, product repairs, and services are warranted for 90 days. This warranty extends only to the original buyer or end-user customer of a Fluke authorized reseller, and does not apply to fuses, disposable batteries, or to any product which, in Fluke's opinion, has been misused, altered, neglected, contaminated, or damaged by accident or abnormal conditions of operation or handling. Fluke warrants that software will operate substantially in accordance with its functional specifications for 90 days and that it has been properly recorded on non-defective media. Fluke does not warrant that software will be error free or operate without interruption.

Fluke authorized resellers shall extend this warranty on new and unused products to enduser customers only but have no authority to extend a greater or different warranty on behalf of Fluke. Warranty support is available only if product is purchased through a Fluke authorized sales outlet or Buyer has paid the applicable international price. Fluke reserves the right to invoice Buyer for importation costs of repair/replacement parts when product purchased in one country is submitted for repair in another country.

Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair, or replacement of a defective product which is returned to a Fluke authorized service center within the warranty period.

To obtain warranty service, contact your nearest Fluke authorized service center to obtain return authorization information, then send the product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination). Fluke assumes no risk for damage in transit. Following warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke determines that failure was caused by neglect, misuse, contamination, alteration, accident, or abnormal condition of operation or handling, including overvoltage failures caused by use outside the product’s specified rating, or normal wear and tear of mechanical components, Fluke will provide an estimate of repair costs and obtain authorization before commencing the work. Following repair, the product will be returned to the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges (FOB Shipping Point).

THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY CAUSE OR THEORY.

Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of incidental or consequential damages, the limitations and exclusions of this warranty may not apply to every buyer. If any provision of this Warranty is held invalid or unenforceable by a court or other decision-maker of competent jurisdiction, such holding will not affect the validity or enforceability of any other provision.

LIMITES DE GARANTIE ET DE RESPONSABILITE

La société Fluke garantit l’absence de vices de matériaux et de fabrication de ses produits dans des conditions normales d’utilisation et d’entretien. La période de garantie est de deux ans et prend effet à la date d’expédition. Les pièces, les réparations de produit et les services sont garantis pendant une période de 90 jours. Cette garantie ne s’applique qu’à l’acheteur d’origine ou à l’utilisateur final s’il est client d’un distributeur agréé par Fluke, et ne s’applique pas aux fusibles, aux batteries/piles interchangeables ni à aucun produit qui, de l’avis de Fluke, a été malmené, modifié, négligé, contaminé ou endommagé par accident ou soumis à des conditions anormales d’utilisation et de manipulation. Fluke garantit que le logiciel fonctionnera en grande partie conformément à ses spécifications fonctionnelles pendant une période de 90 jours et qu’il a été correctement enregistré sur des supports non défectueux. Fluke ne garantit pas que le logiciel est exempt d’erreurs ou qu’il fonctionnera sans interruption.

Les distributeurs agréés par Fluke appliqueront cette garantie à des produits vendus neufs et qui n’ont pas servi, mais ne sont pas autorisés à offrir une garantie plus étendue ou différente au nom de Fluke. Le support de garantie est offert uniquement si le produit a été acquis par l’intermédiaire d’un point de vente agréé par Fluke ou bien si l’acheteur a payé le prix international applicable. Fluke se réserve le droit de facturer à l’acheteur les frais d’importation des pièces de réparation ou de remplacement si le produit acheté dans un pays a été expédié dans un autre pays pour y être réparé.

L’obligation de garantie de Fluke est limitée, au choix de Fluke, au remboursement du prix d’achat, ou à la réparation/remplacement gratuit d’un produit défectueux retourné dans le délai de garantie à un centre de service agréé par Fluke.

Pour avoir recours au service de la garantie, mettez-vous en rapport avec le centre de service agréé Fluke le plus proche pour recevoir les références d’autorisation de renvoi, ou envoyez le produit, accompagné d’une description du problème, port et assurance payés (franco lieu de destination), à ce centre de service. Fluke décline toute responsabilité en cas de dégradations survenues au cours du transport. Après la réparation sous garantie, le produit est renvoyé à l’acheteur, frais de port payés d’avance (franco lieu de destination). Si Fluke estime que le problème est le résultat d’une négligence, d’un traitement abusif, d’une contamination, d’une modification, d’un accident ou de conditions de fonctionnement ou de manipulation anormales, notamment de surtensions liées à une utilisation du produit en dehors des spécifications nominales, ou de l’usure normale des composants mécaniques, Fluke fournira un devis des frais de réparation et ne commencera la réparation qu’après en avoir reçu l’autorisation. Après la réparation, le produit est renvoyé à l’acheteur, en port payé (franco point d’expédition) et les frais de réparation et de transport lui sont facturés.

LA PRESENTE GARANTIE EST EXCLUSIVE ET TIENT LIEU DE TOUTES AUTRES GARANTIES, EXPRESSES OU IMPLICITES, Y COMPRIS, MAIS NON EXCLUSIVEMENT, TOUTE GARANTIE IMPLICITE DE VALEUR MARCHANDE OU D’ADEQUATION A UN USAGE PARTICULIER. FLUKE NE POURRA ETRE TENU RESPONSABLE D’AUCUN DOMMAGE PARTICULIER, INDIRECT, ACCIDENTEL OU CONSECUTIF, NI D’AUCUN DEGAT OU PERTE, DE DONNEES NOTAMMENT, SUR UNE BASE CONTRACTUELLE, EXTRA-CONTRACTUELLE OU AUTRE.

Etant donné que certaines juridictions n’admettent pas les limitations d’une condition de garantie implicite, ni l’exclusion ou la limitation des dommages directs ou indirects, il se peut que les limitations et les exclusions de cette garantie ne s’appliquent pas à chaque acheteur. Si une disposition quelconque de cette garantie est jugée non valide ou inapplicable par un tribunal ou un autre pouvoir décisionnel compétent, une telle décision n’affectera en rien la validité ou le caractère exécutoire de toute autre disposition.

BESCHRÄNKTE GARANTIE UND HAFTUNGSBEGRENZUNG

Fluke gewährleistet, dass jedes Fluke-Produkt unter normalem Gebrauch und Service frei von Material- und Fertigungsdefekten ist. Die Garantiedauer beträgt zwei Jahre ab Versanddatum. Ersatzteile, Produktreparaturen und Servicearbeiten haben eine Garantie von 90 Tagen. Diese Garantie wird ausschließlich dem Ersterwerber bzw. dem Endverbraucher, der das betreffende Produkt von einer von Fluke autorisierten Verkaufsstelle erworben hat, geleistet und erstreckt sich nicht auf Sicherungen, Einwegbatterien oder irgendwelche anderen Produkte, die nach dem Ermessen von Fluke unsachgemäß verwendet, verändert, vernachlässigt, verunreinigt, durch Unfälle beschädigt oder abnormalen Betriebsbedingungen oder einer unsachgemäßen Handhabung ausgesetzt wurden. Fluke garantiert für einen Zeitraum von 90 Tagen, dass die Software im Wesentlichen in Übereinstimmung mit den einschlägigen Funktionsbeschreibungen funktioniert und dass diese Software auf fehlerfreien Datenträgern gespeichert wurde. Fluke übernimmt jedoch keine Garantie dafür, dass die Software fehlerfrei ist und störungsfrei arbeitet.

Von Fluke autorisierte Verkaufsstellen dürfen diese Garantie ausschließlich für neue und nicht benutzte, an Endverbraucher verkaufte Produkte leisten. Die Verkaufsstellen sind jedoch nicht dazu berechtigt, diese Garantie im Namen von Fluke zu verlängern, auszudehnen oder in irgendeiner anderen Weise abzuändern. Der Käufer hat nur dann das Recht, aus der Garantie abgeleitete Unterstützungsleistungen in Anspruch zu nehmen, wenn das Produkt bei einer von Fluke autorisierten Vertriebsstelle erworben oder der jeweils geltende internationale Preis gezahlt wurde. Fluke behält sich das Recht vor, dem Käufer Einfuhrgebühren für Ersatzteile in Rechnung zu stellen, falls der Käufer das Produkt nicht in dem Land zur Reparatur einsendet, in dem er das Produkt ursprünglich erworben hat.

Die Garantieverpflichtung von Fluke beschränkt sich darauf, dass Fluke nach eigenem Ermessen den Kaufpreis ersetzt oder aber das defekte Produkt unentgeltlich repariert oder austauscht, wenn dieses Produkt innerhalb der Garantiefrist einem von Fluke autorisierten Servicezentrum zur Reparatur übergeben wird.

Um die Garantieleistung in Anspruch zu nehmen, wenden Sie sich bitte an das nächstgelegene von Fluke autorisierte Servicezentrum, um Rücknahmeinformationen zu erhalten, und senden Sie dann das Produkt mit einer Beschreibung des Problems und unter Vorauszahlung von Fracht- und Versicherungskosten (FOB-Bestimmungsort) an das nächstgelegene von Fluke autorisierte Servicezentrum. Fluke übernimmt keine Haftung für Transportschäden. Im Anschluss an die Reparatur wird das Produkt unter Vorauszahlung der Frachtkosten (Frachtfrei-Bestimmungsort) an den Käufer zurückgesandt. Wenn Fluke feststellt, dass der Defekt auf Vernachlässigung, unsachgemäße Handhabung, Verunreinigung, Veränderungen am Gerät, einen Unfall oder auf anormale Betriebsbedingungen, einschließlich durch außerhalb der für das Produkt spezifizierten Belastbarkeit verursachter Überspannungsfehler oder normaler Abnutzung mechanischer Komponenten, zurückzuführen ist, wird Fluke dem Erwerber einen Voranschlag der Reparaturkosten zukommen lassen und erst die Zustimmung des Erwerbers einholen, bevor die Arbeiten in Angriff genommen werden. Nach der Reparatur wird das Produkt unter Vorauszahlung der Frachtkosten an den Käufer zurückgeschickt, und es werden dem Käufer die Reparaturkosten und die Versandkosten (Frachtfrei-Versandort) in Rechnung gestellt.

In einigen Ländern ist die Begrenzung einer gesetzlichen Gewährleistung und der Ausschluss oder die Begrenzung von Begleit- oder Folgeschäden nicht zulässig, sodass die oben genannten Einschränkungen und Ausschlüsse möglicherweise nicht für jeden Käufer gelten. Sollte eine Klausel dieser Garantiebestimmungen von einem zuständigen Gericht oder einer anderen Entscheidungsinstanz für unwirksam oder nicht durchsetzbar befunden werden, so bleiben die Wirksamkeit oder Durchsetzbarkeit anderer Klauseln dieser Garantiebestimmungen von einem solchen Spruch unberührt.

GARANZIA LIMITATA E LIMITAZIONE DI RESPONSABILITÀ

Si garantisce che ogni prodotto Fluke è esente da difetti nei materiali e nella manodopera per normali situazioni di uso. II periodo di garanzia è di due anni a decorrere dalla data di spedizione. La garanzia sulle parti sostituite, sulle riparazioni e sugli interventi di assistenza è di 90 giorni. La garanzia è valida solo per l’acquirente originale o l’utente finale che abbia acquistato il prodotto presso un rivenditore Fluke autorizzato. Sono esclusi i fusibili, le pile monouso e i prodotti che, a parere della Fluke, siano stati adoperati in modo improprio, alterati, trascurati, contaminati o danneggiati in seguito a incidente o condizioni anomale d’uso e maneggiamento. La Fluke garantisce che il software funzionerà sostanzialmente secondo le specifiche per un periodo di 90 giorni e che è stato registrato su supporti non difettosi. Non garantisce che il software sarà esente da errori o che funzionerà senza interruzioni.

I rivenditori autorizzati Fluke estenderanno la garanzia sui prodotti nuovi o non usati esclusivamente ai clienti finali, ma non potranno emettere una garanzia differente o più completa a nome della Fluke. La garanzia è valida solo se il prodotto è stato acquistato attraverso la rete commerciale Fluke o se I’acquirente ha pagato il prezzo internazionale pertinente. La Fluke si riserva il diritto di fatturare all’acquirente i costi di importazione per la riparazione/sostituzione delle parti nel caso in cui il prodotto acquistato in un Paese sia sottoposto a riparazione in un altro.

L’obbligo di garanzia è limitato, a scelta della Fluke, al rimborso del prezzo d’acquisto, alla riparazione gratuita o alla sostituzione di un prodotto difettoso che sia inviato ad un centro di assistenza autorizzato Fluke entro il periodo di garanzia.

Per usufruire dell’assistenza in garanzia, rivolgersi al più vicino centro di assistenza autorizzato Fluke per ottenere informazioni sull’autorizzazione alla restituzione, quindi spedire il prodotto al centro di assistenza, allegando una descrizione del difetto, franco destinatario e assicurato. La Fluke declina ogni responsabilità di danni durante il trasporto. Una volta eseguite le riparazioni in garanzia, il prodotto sarà restituito all’acquirente, franco destinatario. Se la Fluke stabilisce che il guasto è stato causato da negligenza, uso improprio, contaminazione, alterazione, incidente o condizioni anomale di uso o maneggiamento (comprese le sovratensioni causate dall’uso dello strumento oltre la portata nominale e l’usura dei componenti meccanici dovuta all’uso normale dello strumento), la Fluke darà una stima dei costi di riparazione e attenderà l’autorizzazione dell’utente prima di procedere con la riparazione. A seguito della riparazione, il prodotto sarà restituito all’acquirente con addebito delle spese di riparazione e di spedizione.

LA PRESENTE GARANZIA È L’UNICO ED ESCLUSIVO RICORSO DISPONIBILE ALL’ACQUIRENTE ED È EMESSA IN SOSTITUZIONE DI OGNI ALTRA GARANZIA, ESPRESSA O IMPLICITA, COMPRESA , MA NON LIMITATA A ESSA, QUALSIASI GARANZIA IMPLICITA DI COMMERCIABILITÀ O DI IDONEITÀ PER SCOPI PARTICOLARI. LA FLUKE NON SARÀ RESPONSABILE DI NESSUN DANNO O PERDITA SPECIALI, INDIRETTI O ACCIDENTALI, DERIVANTI DA QUALUNQUE CAUSA O TEORIA.

Poiché alcuni Paesi non consentono di limitare i termini di una garanzia implicita né l’esclusione o la limitazione di danni accidentali o indiretti, le limitazioni e le esclusioni della presente garanzia possono non valere per tutti gli acquirenti. Se una clausola qualsiasi della presente garanzia non è ritenuta valida o attuabile dal tribunale o altro foro competente, tale giudizio non avrà effetto sulla validità delle altre clausole.

Fluke 授权的零售商应仅对最终用户就新的和未使用的产品提供本担保，但无权代表Fluke 公司提供额外或不同的担保。只有通过 Fluke 授权的销售店购买的产品或者买方已经按适用的国际价格付款才能享受 Fluke 的担保支持。在一国购买的产品需在他国修理时，Fluke 有权向买方要求负担重大修理/零件更换费用。

Fluke 的担保为有限责任，由 Fluke 决定是否退还购买金额、免费修理或更换在担保期间退还 Fluke 授权服务中心的故障产品。

Power Quality Logger

Introduction

The Fluke 1745 Power Quality Logger, see Figure 1, is a sophisticated, easyto-use, electrical power-recording device for the electrician or power-quality specialist.

Note

This manual also refers to the 1745 Power Quality Logger simply as “the Logger”.

The Logger conatins an automatically charged 8-hour UPS (uninterruptable power supply) battery for long-term voltage interruption ride-through, and an LCD status display to provide confidence in setup before you leave the Logger in place to collect data.

You can power the logger in parallel with the test leads or through an outlet. Adapter cords for both methods of power in the Logger are included as standard equipment.

You’ll prepare the Logger for use with the included PQ Log software. You can then connect the Logger to an electrical power-distribution network to log a variety of power parameters, recorded as sequential averaged values over an averaging period you can define. The Logger can measure up to three voltages and four currents simultaneously.

Information and PC Software CD

The CD included with the Logger contains the PQ Log application software for Windows, along with users manuals in multiple languages.

The PQ Log software prepares the Logger for use, and downloads data from the Logger to a connected PC.You can then view the logged data in graphical and tabular form, export it to a spreadsheet, or create reports for printing. For details and instructions, see the PQ Log Users Manual on the CD.

Logger Power Supply

The Logger does not include a power switch, but turns on automatically whenever its power supply leads are connected to a voltage in its allowed range. You can plug the Logger’s power supply leads into a standard wall outlet (using the included adapter cord), or you can connect them directly to the power network under test (in parallel with the test leads) if there is no convenient wall outlet (only if the voltage at the test leads is below 660V RMS.)

Logging Functions

The Logger monitors power quality and locates disturbances in low and medium voltage distribution networks. It measures up to 3 voltages and 4 currents. Logged values are saved in your choice of sequential averaging periods. You graphically or numerically evaluated measured values with PQ Log.

The Logger has two types of logging functions: logging function A (Advanced) and logging function P (Power). Function A is the full set of parameters, and function P provides logging capability optimized for load studies and basic power logging. Function P contains every parameter in Function A except voltage and current harmonics and interharmonics. Logging function P allows longer logging periods because it does not save harmonics values.

Power Quality Logger

Introduction

Logging function parameters:

• RMS Voltage of each phase (average, min, max)

• RMS Current of each phase and neutral (average, min, max)

• Voltage events (dips, swells, interruptions)

• Power (kW, kVA, kVAR, Power PF, Power tangent)

• Energy, total energy

• Flicker (Pst, Plt)

Test Leads - Markings

The 1745 Logger includes detachable labeled test leads for voltage terminals L1 or A, L2 or B, L3 or C, and N. Another detachable set of leads provides operating power to the Logger. The Flexi Set or current clamp sets are connected by a seven-pin plug to the Logger A connector. Color coding clips are provided for your convenience. Table 5 shows the test leads and markings of the Logger.

Connecting Current Probes

Connect current clamps and Flexi Set probes so that current will flow in the direction marked by arrows on the probes. Current must flow from the energy generator to the energy consumer (the load) in order to maintain a positive active power. Orient the Flexi probe so that the arrow points towards the load. (The polarization of the test lead for neutral conductor current is not significant, because the phase angle of the neutral conductor current is not evaluated.)

Logging with Voltage Converters

The 1745 Logger includes an adjustable convertor ratio that enables it to be used with voltage convertors (potential transformers, or PTs).

Note

When logging with voltage convertors, make sure the power supply cables are not connected in parallel to the voltage test leads, or the Logger’s power consumption can reduce accuracy.

The convertor ratio is defined using the PQ Log software.

Logging

When the Logger is connected and ready, you can perform three types of logging:

Switch-activated job: The status LED is blinking. Press the

START/STOP button once. As soon as the job is active, the LED is on continuously. If needed, the job can be cancelled after running for at least one minute, and restarted later.

Time-activated job: The Logger starts logging as soon as the pre-

programmed start time is reached and stops at the defined end time.

Immediate job: The Logger starts logging as soon as power is on.

Note the following about logging jobs:

1. The connection can be verified with the LCD (voltage, current,

power). If all three LEDs are lit continuously, the voltage connections and signal levels are within nominal range. For details, see Table 4 in the Features section.

2. The Logging job status is indicated by the status LED. For details, see

Table 4 in the Features section.

Completing the Logging Job

1. Terminate the job as follows:

• For switch activated jobs: At the end of the logging period,

stop the logging job by pressing the START/STOP button.

• For time activated and immediate jobs: Stop the job in PQ

Log with the icon, or with menu Logger/Stop logging

Note

Make sure the logging job is stopped with the START/STOP button (switch activated jobs) or PQ Log (time activated jobs) before the terst leads or power supply leads are removed. Otherwise, the Logger will record a voltage interruption.

Only switch-activated jobs can be aborted. Time activated jobs are terminated only when the programmed measuring time has elapsed.

The Logger can be programmed to record up to five interharmonics with a resolution of 5 Hz. This function can also be used to monitor ripple-control signals by entering the signal frequency of the local utility.

The Logger measures the three second RMS value of each interharmonic and establishes statistics for EN50160 (European standard) evaluation. These statistics are available after a minimum recording time of 24 hours, or after regular termination of the measuring job and can be exported from PQ Log and evaluated later.

Additionally, the Logger provides a long term recording of the interharmonics. You can select from the following special measurement methods in the PQ Log software:

• 200 ms maximum value (recommended for estimating ripple-control

signal levels)

• 200 ms minimum value

• 3 seconds maximum value

• Average value over interval

In PQ Log, the frequency can be entered with a resolution of 0.5 Hz, but for evaluation, the values are corrected to a bandwidth of 5 Hz. One frequency can be defined for each band: for example, for a ripple-control signal of 183 Hz, the values will be corrected to 185 Hz). Interharmonics of voltages and currents with these frequencies are recorded.

See the PQ Log manual for details.

Flicker

Flicker is the visual impression of unsteadiness in a light source whose luminance or spectral distribution changes over time. Flicker, see Figure 14, is logged in accordance with the IEC 61000-4-15 standard. The short-term (st) flicker P to calculate the long-term (lt) flicker P

is logged over a default standard interval of 10 minutes, and is used

by taking the sliding average of 12

short term values. The interval value can be changed as needed in PQ Log.

Unbalance

The ratio of negative-to-positive-sequence harmonics is calculated with the angles and magnitudes of the phase voltages taken into account. These values are averaged over the interval length defined in PQ Log.

Frequency

The line power frequency is measured and averaged over 10 seconds and the resulting values are divided into 42 classes for establishing statistics. Values are also averaged over the interval length defined in PQ Log.

Current Logging

The maximum values of the currents (L1 or A, L2 or B, L3 or C and N) are measured, and the interval value of the current is calculated using the mean value over the RMS values of the interval defined in PQ Log.

Logging Function A

If a 3-phase current sensor is connected, the neutral current is calculated on a sample basis from the phase currents. If a 3-phase+N sensor is detected, you can select between logging and calculating the neutral current in PQ Log.

Ipeak

The peak values of the current (samples, not RMS values) are averaged in the PQ Log software over the predefined measuring interval.

Note

Short peak values do not contribute much to the average value and so I be higher than I

Crest Factor (CF)

The crest factor (CF) of the currents (L1 or A, L2 or B, L3 or C, and N) is the ratio of current peak value divided by current RMS value, and is averaged over the interval length defined in PQ Log. For sinusoidal signals, CF = 1.41, and for square waves, CF =1.00

Power

The power values (L1 or A, L2 or B, L3 or C and N) are averaged over the interval length, and the maximum value of each is recorded.

The response time can be set to 1 second or 1 minute, and is independent of the response time for voltage and current.

In logging function P, the active power, apparent power, and reactive power of the phases and total power of all three phases is calculated.
